ITEM CONDITION

This PCV Valve, or Positive Crankcase Ventilation valve, is a new, aftermarket replacement part. It is an emission control device that routes unburned crankcase blowby gases back into the intake manifold where they can be reburned. The PCV system is one of the oldest emission control devices, and also one of the most beneficial. Besides totally eliminating crankcase emissions as a source of air pollution, the constant recirculation of air through the crankcase helps remove moisture which otherwise would cause sludge to form. Thus the PCV valve extends the life of the oil and engine. The PCV valve requires little maintenance. The valve and filter should be replaced somewhere around 30,000 to 50,000 miles (see your vehicle owners manual for service intervals).

Most PCV valves are located near the valve cover and can be easily replaced. The way to tell if your PCV valve is bad is not just to shake it, but trying to suck, or blow, air in both directions. If the valve is good, it should allow air to only move in one direction. If no air can move through it or air can move through it in both directions (it should be one-way), then it needs to be replaced.
